According to the world energy policy, running out of fossil energies is not so important. Because Greenhouse Gas (GHG) emission and energy consumption rate are in the first priority that is why today the global warming is a very serious crises. In addition, Internal Combustion Engine (ICE) cars play a big role in the Sulfur dioxide (SO2) on the world and its density is in high level in metropoles. Consequently, in this paper, analyzing these problems from mentioned aspects in Ankara city are investigated. Ankara is one of the most polluted cities in Turkey and back in the time; the city air was polluted by 808 ton per year SO2 in 1992 and 424,129 cars existed in Ankara at 1995. To get approximately how much SO2 emission could be decreased and what infrastructure in the grid could response Electric Vehicles (EV) in this city. According to electric vehicle charge station coordinating, side effects of the EVs to grid are investigated.
